Commit: fixed - Superscript (run?) bug

[Martin Sevior]

Fixed Jamies superscript bug.Sometimes you can be right first time :-) The
text position information was not being passed to the new run after a
split from a line break.

It was a one line fix in 

UT_Bool fp_TextRun::split

I added the line:

        pNew->m_fPosition = this->m_fPosition;

If only they were all this easy.

Cheers

Martin
